I work as a courier in ZTO Express Company, but recently I'm afraid to make a phone call. I dare not speak when others are on the phone. What should I do?

I suggest you take the stereo to the roadside to sing, sing one and run away. After a few times, you will exercise your skin, so that you will never make the disease you said, or you can speak loudly in a vegetable market or supermarket and give you a four-leaf clover. Good luck!
